GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

2018 GMC Terrain loses the V6 and gains a diesel for an all-turbo lineup

You may have noticed that compact crossovers are kind of a big deal these days. After eight years on sale, GMC is finally getting a new version of its littlest ute, the Terrain, for 2018. And it can't arrive a moment too soon. The 2018 GMC Terrain made its debut tonight on the eve of the 2017 Detroit Auto Show. The 2018 Terrain looks to be completely new, and is now built on GM's D2XX platform. It again shares a platform and major components with the Chevrolet Equinox; like the 2018 Equinox, the Terrain will offer three engines, including two turbocharged gas four-cylinders and a turbodiesel four. The base 1.5-liter gas four makes 170 horsepower and 203 pound-feet of torque, while the 2.0-liter inline-four puts out 252 hp and 262 lb-ft. (The 2.0 basically takes the place of the 3.6-liter V6 offered in the outgoing Terrain.) GM's 1.6-liter diesel four will also be available, making 137 hp and 240 lb-ft of torque in this application. Both gas engines will be paired with nine-speed automatic transmissions, while the diesel gets a six-speed auto. No fuel-economy claims have been made, but we expect the new models to outdo the current versions, with the diesel reaching around 40 mpg on the EPA highway cycle. View 14 Photos The new Terrain's design is equally fresh and does a good job of differentiating it from the related Equinox, with details very reminiscent of the new GMC Acadia. The lighting elements are even more intricate here, with LEDs used for the daytime running lights and taillamps. GMC designers gave it the floating-roof look, which is successful aside from the odd placement of a trim badge at the base of the D-pillar. Terrains will again be available in SL, SLE, SLT, and range-topping Denali trim, with the latter featuring the signature satin chrome grille, chrome accents, and monochrome paint scheme GMC uses on all of its top-trim models. The interior sees an upgrade in materials and a more-thoughtful layout, with a new version of GM's Electronic Precision Shift gear selector using buttons and switches instead of a lever to open up more space on the center console. Both front- and all-wheel-drive models get a Traction Select system that will tune the shift points and throttle points for specific driving conditions via a knob at the rear of the console. On models equipped with all-wheel drive, a front-drive mode disconnects the rear axle to improve fuel economy.

GMC Hummer EV pickup reveal postponed

We’re pretty excited about the all-electric Hummer pickup coming from the GMC brand. GM is too, enough to spend Super Bowl money on an ad teasing it. Today, we received an update from GM about the Hummer EV, with good news and bad news. The bad news: GM has announced that it is postponing the May 20 reveal for the Hummer. With the coronavirus throwing the proverbial wrench into a number of vehicle operations, including reveals, we canÂ’t say weÂ’re surprised at all. The good news, GM assures us, is that development continues “undeterred.” GM understandably hasnÂ’t provided a new debut date for the GMC Hummer EV, but it did provide us with the new short teaser video above. WeÂ’ve seen other details in previous teasers, as well. We were lucky enough to see the Hummer EV in person last month just before the pandemic began causing the world to grind to a halt. At GMÂ’s EV Day at its Warren, Mich., campus, the Hummer pickupÂ’s exterior was on full display. ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel. The Hummer pickup will be offered with a number of electric powertrain options, the most powerful of which will provide 1,000 horsepower and a 0-60 mph time of less than three seconds. Like the rest of the next generation of GM EVs, it will use the automakerÂ’s new Ultium modular battery and powertrain technology. While we donÂ’t have further details about a potential reveal date, we also know a Hummer electric SUV based on the pickup will follow at some point. It, too was on display at GMÂ’s EV Day. It looks exactly like the Hummer pickup from the rear doors forward, but with a shorter wheelbase and enclosed cargo area in the rear. It also sported a liftgate-mounted spare.
